Participants

Reaction Steps

In like manner to the preparation of N4-(3-chloro-4-trifluoromethoxyphenyl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidineamine, the reaction of 3-hydroxyaniline with 2-chloro-N4-(2,6-dimethoxypyridin-3-yl)-5-fluoro-4-pyrimidineamine gave N4-(2,6-dimethoxypyridin-3-yl)-5-fluoro-N2-(3-hydroxyphenyl)-2,4-pyrimidinediamine. 1H NMR (DMSO-d6): δ 9.98 (bs, 2H), 8.20 (d, 1H, J=5.4 Hz), 7.72 9m, 1H), 6.90 (t, 1H, J=7.8 Hz), 6.81 (m, 2H), 6.42 (m, 2H), 3.88 (s, 3H), 3.86 (s, 3H); LCMS: purity: 94%; MS (m/e): 358 (MH+).
